INSTRUCTIONS. 19 To Order No. PC 16 (2) Customer's No. Summing up, then, we have as follows:- 1 All condensers, when heated, acquired an increase in capacity. 2 That the general tendency at atmospheric temperatures was to retain this increase 3 That even when subjected to a low temperature for some hours they were unaffected. i.e they did not return to normal. 4 But after a comparatively long period, during which the average atmospheric temperature has been lower than before, there are signs of the condensers returning to their original capacity values. Signed C.H.P. This Sheet must be filed on completion of the work. | ||
